I doubt anyone would be making jokes about Poles in school today. That particular flavor of racism has almost entirely died out in younger generations.

As for picking someone up, yeah, that would be a big problem. Regardless of the efficacy of it, it’s still technically battery, just as it was back then. And to be fair, corporal punishment doesn’t really teach any valuable lessons, it just makes people scared of those who are bigger than them. They still do the bad thing they were punished for, they just get creative to avoid getting found out by the people who can punish them. Then they grow up to be Karens who push people around for stupid shit like not giving them enough sauce with their hamburger.

If corporal punishment did work, boomers would be the most polite generation out there.
